PG311-PG314 Pattern Generator


The MicroImage PG311/PG314 series of pattern generators are for applications to display custom designed patterns on screen. The PG311/PG314 units will overlay the pattern or patterns on top of the video signal provided to the input of the device. The PG311 can be factory programmed with one unique pattern, while the PG314 can hold up to four patterns and switch between them.

The pattern image files can be sent to the factory as a bit mapped file, in GIF, TIFF, BMP and other formats. JPEG is not an acceptable format. The resolution can be either 320x240x1 or 640x480x1 for NTSC. For PAL, the resolution is 384x288 or 768x576 (only up to 512 of the 576 lines addressable in PAL).

The units have switches for Pattern Display on/off, Power on/off and a rotary control to change the brightness of the pattern. The PG314 also has individual switches to select each pattern.

Units are available to function with a variety of video signals. The PG311/PG314 work with composite, B&W and S-Video signals. The PG311N and PG314N work with the NTSC/RS170 sync system, while the PG311P and PG314P operate with PAL/CCIR.

Power is provided by a universal power module (included) or the unit can be powered from +12VDC (negative ground). DC power consumption is about 3 watts. The unit is packaged in a durable metal enclosure with plastic bezel assemblies.

The PG series of Pattern Generators are also available as board level products. These can be provided with the standard connectors listed above or small single row "header" connectors. MicroImage Video Systems can also provide custom units to meet unique requirements. Please contact MicroImage Engineering for additional information.

The PG311 and PG314 have a one year parts and labor limited warranty.
